For my own personal use here, I think I'm going to go with option number 2, for a couple reasons. I mean, things contradict scientific laws all the time, including scientists, so that's just out of the picture. The second definition, however, is simple and to the point; "A remarkable thing." Because really, that's what a miracle is. People usually think of miracles as things like someone overcoming cancer against all odds or walking away from a terrible car accident without a scratch. They're right too, those are miracles, however, they're forgetting the small things in life.
Miracles happen everyday. They really do. Take a second to think about it. A baby being born. A person deciding to stay home so they can avoid a bad decision. A tree being planted. Choosing forgiveness over revenge.
Heck, life itself is a miracle. Really, take a second to think about this one too. The budding leaf of a tree- do you know what that tree has to do to produce that single leaf? It's incredible. Animals too- a mammal fetus starts off as a single cell inside the mother, multiplying over and over again to produce an incredibly complex creature. It's truly remarkable; a miracle.
People (myself included) ask for miracles all the time. We pray for them, demand them, even try to make them ourselves. We're never really satisfied with the results either. I think, though, we actually receive miracles more often than we think. I mean, what if we're just not looking in the right places? I know the saying "God works in mysterious ways" is probably way overused, but that's how it really is. Unfortunately for us, His plan is about a billion times bigger than anything we could ever possibly dream up, and we just don't get it. There's a ton of bad in this world, but He does everything for a reason. Now I'm not saying that cancer is a product of God, I don't believe that at all. The bad in this world is the result of the devil and our own sins. God, however, has provided us with a way out- Jesus Christ. We follow Him and we're saved. Not necessarily in this life, but that's not what's important- where your soul is going to spend eternity (also way bigger than our wildest imaginations) is what really matters.
Just because the big miracle you were hoping for didn't happen doesn't mean God wasn't there; it doesn't even mean there wasn't a miracle. Maybe you just need to look at the bigger picture. So next time you ask for a miracle, look around a little harder. The answer you get might be closer than you think.
